Description
Gene for the B subunit of the LsrACDB transporter, present in E. coli on the LsrACDBFG operon. The B subunit is the autoinducer 2 (AI-2) binding protein in the transporter, which actively brings AI-2 into the cell.
Notes
The portion of the LsrACDBFG operon that codes for the AI-2 transporter consists of four open reading frames, which code for A, C, D, and B, respectively. Three of these ORFs overlap with one another: C overlaps with A, and its RBS is contained within the A subunit ORF, and D overlaps with C (although to a lesser extent), and its RBS is contained within the C subunit ORF. From a modularization standpoint, this creates an inefficiency because the wild type ORFs of the A and C subunits both contain functional RBSs, and in the case of the A subunit ORF, an ATG 4bp downstream. To reduce this inefficiency, we have created versions of each subunit ORF that are optimized for modularization. Further explanation is available in the descriptions of those parts.
